Blocklist

Below is my current Apache Comment Spam blocklist, please help yourselves. In addition I also use the Spamhaus DROP List at a firewall level to further reduce spam.

Everyone on this list has generated enough comment spam to be worth my while blocking outright, you may have different views on blacklisting all ranges assigned to a particular AS, but as far as I’m concerned if neither the hosting provider nor their upstream provider (where they’re not the same entity) care enough to stop spammers on one of their netblocks, they’re unlikely to do anything about any of the others either.

Ranges are collapsed wherever possible.

With the best will in the world false positives will happen so if, for some reason, you feel you or your organisation have been added to this list in error, please contact admin@angryadmin.co.uk and I’ll review your inclusion.

Additional: Not technically spam but it falls into the same group of irritating arseholes as far as I’m concerned, Semalt; Semalt is an SEO service based in Ukraine who crawl sites using a bot that disguises itself as a regular user (Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.107 Safari/537.36) and shows up constantly in your referrer logs (e.g. http://semalt.semalt.com/crawler.php?u=http://angryadmin.co.uk) from a variety of IP addresses from different netblocks. Everything I can find about these guys is fishy, the way their crawler behaves is contrary to all good practices for these things and the randomness of the IP addresses screams “botnet”. If you are having issues with Semalt and want to block them from your site, you can use mod_rewrite to block their referrer and redirect them to a 403 page by using the following in your .htaccess or sites .conf file

Hi!
Does this list works in htaccess, WordPress? Mine and everyone else’s problem is this Chinese HAIYAN ZHANG, PEG TECH INC. This company must be the most hated ever in the world when it comes to spam.
👿

Question from a less informed viewer:
This is a lot of info to be throwing into an htaccess file. Does is slow things down (significantly?) And does anyone have experience with ZB Block and its effectiveness?
Thanks in advance.

This is not a general purpose blocklist, it’s certainly not an email blocklist, it is a comment spam blocklist and should only be used as such so I’ve no idea why you’re bringing MTAs into this.

“Legitimate” is a matter of opinion but nonetheless *all* of the providers I’ve listed are responsible for hosting significant numbers of comment spam bots. Now sure, you might argue that “it’s just one or two compromised hosts” but a) almost every time I’ve taken one of these netblocks off my blocklist I’ve immediately started getting comment spam from them again and b) 95% of the listed netblocks belong to hosting providers rather than residental or business ISPs and so you should never really be getting any legitimate comments from them in the first place.

But thank you for rubbishing my list without putting any real thought into it, it’s appreciated.

Thanks for an excellent resource. I found it by searching for Nobis Technology Group before adding them to my own blocklist. Now I’m thinking of just using your list from now on. With that in mind I’ve clicked the box for new post notifications.
